The purpose of the research was to examine children's evaluative reactions to bilingual code switching during a dyadic cross-cultural encounter. Children's reactions to code switching were elicited using a segmented dialogue technique whereby they listened to and judged each of an integrated series of speech turns one at a time in their order of occurrence. The speakers were played by English and French Canadian actors and were depicted in the roles of a salesman and a customer. English and French Canadian children were subjects. It was found that the children's evaluations of the speaker's language choices were influenced by (a) situational norms associated with appropriate salesman and customer behaviours; (b) interpersonal accommodation; and (c) ingroup favouritism, but not by sociocultural status differences between French and English. Moreover, their reactions were dynamic in that they depended upon mutual language choices by both actors and the basis of their evaluations changed from the beginning to the end of the dialogue sequence. The findings are discussed with respect to results from other developmental research using simpler elicitation techniques as well as to findings from adolescent and adult respondents.

Learning disabled children have been found to be less likely than nondisabled children to request clarification of ambiguous messages provided by adults. This study tested a strategy deficit hypothesis as one source of this conversational deficit by assessing the effects of a brief intervention which highlighted the appropriate response strategy, i.e., question-asking. Learning disabled and non-disabled children in grades four, five, and six played the listener role in a referential communication task requiring them to select referents based on messages varying in informational adequacy. Although group and grade differences replicated previous findings, the intervention condition had no effect on the children's performance on a posttest. An analysis of referent selections indicated that the inactive listeners were overrelying on the Maxim of Quantity, the Gricean principle that cooperative speakers provide informative messages. These results suggest that conversational development depends on children's increasing ability to recognize contexts in which these conversational principles do not apply.

We tested 20 language-impaired children, 20 age-matched normal children, and 20 language-matched normal children. In free recall, children simply remembered as many words possible; in cued recall, the experimenter provided the category names as retrieval cues; in repeated free recall, children recalled the list three times in succession. The principal results were that (1) language-impaired children recalled fewer words than their agemates in both free and cued recall, and (2) the pattern of repeated free recall suggested that language-impaired children were less likely than their agemates to store a word when presented, and were less consistent in their retrieval of words. Our discussion concerns the roles of lexical acquisition and lexical retrieval in language-impaired children's word-finding problems.

This study examines the acquisition of production and perception by adult learners of English. The particular focus is voice onset time of initial /b/'s and /p/'s. The subjects are 10 nonnative speakers of English and six native speakers who provided identification responses to synthesized stimuli varying along a voice onset time continuum. Additionally, they each produced words with initial /b/'s and /p/'s. These measures were repeated at three 1-month intervals for the nonnative speakers. The results show that nonnative speaker perception differs from native speaker perception in two important ways: (1) stop consonants are perceived continuously rather than categorically and (2) nonnative speaker perception is influenced by the location of phoneme boundaries in both the native and target languages. Nonnative speaker production shows a greater amount of similarity to native speaker production, although, where deviations occur, nonnative speakers tend to overcompensate for differences between the native and target languages. Finally, methodological issues are raised relating to the comparison of perception and production.
